Samsung has moved closer to the official release of its next generation flagship audio wearables. The Galaxy Buds 4 Pro recently appeared in the Federal Communications Commission (FCC) database under the model number SM-R640. This regulatory filing is a mandatory requirement for electronic communication devices before they can be sold in the United States. The certification lists individual IDs for the left and right units, designated as A3LSMR640L and A3LSMR640R.
Technical data from the FCC documents indicates the earbuds will operate using a 3.85V DC power supply and cover the standard 2402MHz to 2480MHz Bluetooth frequency range. The filings also mention the use of a metal antenna system for wireless connectivity. While the FCC does not typically disclose consumer facing features, the presence of the device in the database suggests that hardware development is complete and mass production is likely underway.
Leaked animations found within One UI 8.5 firmware provide further details on the physical design of the Galaxy Buds 4 Pro. Samsung appears to be moving away from the sharp, triangular stem utilized in the Galaxy Buds 3 Pro in favor of a flatter and more refined stem shape. This redesign is intended to improve ergonomics and touch control reliability. The charging case has also undergone a significant structural change. Rather than dropping the earbuds into vertical slots, the new case allows them to rest horizontally. This box-like configuration is expected to be more pocket-friendly than previous iterations.
Internal specifications reveal a battery capacity upgrade for the Pro model. Each earbud is equipped with a 57mAh battery, which is an increase from the 53mAh cells found in the preceding model. This hardware adjustment, combined with software optimizations in the upcoming One UI 8.5, is expected to extend total playback time. The earbuds will likely continue to support high resolution audio codecs, 360 degree spatial audio, and adaptive active noise cancellation.
Software integration will be a primary focus for this release. Early reports suggest that the Galaxy Buds 4 Pro will introduce head gestures similar to those found on the Apple AirPods Pro. These gestures would allow users to accept or reject calls by nodding or shaking their head. Additionally, the earbuds are expected to feature enhanced Galaxy AI capabilities for real-time language translation and environmental sound processing.
The Galaxy Buds 4 Pro are scheduled to launch in the first quarter of 2026. Industry analysts expect the announcement to coincide with the Galaxy Unpacked event for the Galaxy S26 series, which is rumored for late January or February. While Samsung has not confirmed official pricing, market trends suggest a retail price near $249.99 to $269.99. The earbuds will be available at major retailers and through the official Samsung website following the launch event.
